Furthermore, by forming the skirt of a series of angularly connected friction surfaces so proportioned as to trictionally eugage the outer faces of container projeo tions, this will materially assist in preventing the lugs ot the cap from rotating bacle ward on the container and the consequent premature separation of the cap 'lroin the container during the shipi'nent or handling of the cap. Thus the cap will be maintained on the container both by these :t'ricti on sur faces oi large extent and by the legs, which is of considerable importance in the shipping and packing of containers or in the ordinary handling thereof on the shelves or stores or in the house.

In practice the cap will he provided with an annular groove 7 to contact with a suitable liner not shown, thereby to effect the ellioient sealing of the cap on the container.

I believe I am the first to provide a metal cap having a skirt or flange in which practically all ot' the shirt is oi polygonal. form, so proportioned as to lrictionally engage the outer faces of container projections or which extend from substantially the top to substantially its lower edge of the shirt, and therefore the first to provide a shallow flanged cap of such construction having locking projections at its lower edge, and also such a cap having a strengthened lower edge provided with locking lugs formed therefrom.

It is to be understood that by describing in detail herein any particular form, structure, or arrangement, it is not intended to limit the invention beyond the terms of the several claims or the requirements ot the prior art.

Having thus explained the nature of my said invention and described a way of constructing and using the same, although without attempting to set forth all of the terms in which it may be made, or all of the modes of its use, I claim:

1. A combined lag and friction holding container cap of metal comprising a top and a shallow depending polygonally termed flange or skirt having a rolled, curled or beaded lower edge provided with inwardly extending locking lugs it'orined therefrom adapted to engage under inclined container projections, such polygonal formation being so proportioned as to frictionally engage the outer faces of said inclined container projections and prevent the premature bacle ward rotation of the cap.

2. A container cap comprising a top and a de u-mding polygonally formed flange or skirt of metal, such polygonal formation ea:- tending from substantially the top of the cap toits lower edge on the inside oi said skirt and so proportioned as to frictionally engage the outer faces of container projections.

:3. A container cap comprising a top and a depending polygonally formed shallow flange or skirt of metal having a strengthened lower edge, such polygonal formation extendii'ig "from substantially the top (it the cap to its strengthened lower edge on the inside ot said skirt and so proportioned as to trictionally engage the outer faces of container projections.

at. A container cap com n'ising a top and a depending polygonally formed shallow llange or skirt of metal, such polygonal :l'ormation extending from substantially the top oi the cap to its lower edge on the inside oi. the skirt and so proportioned as to :lrictionally engage the outer faces of containcr projections, and locking projections below said polygonal surfaces.

5. A container cap comprising a top and :1 depending polygonally termed shallow flange or skirt ot' metal having a rolled, curled or beaded lower edge having inwardly extending locking projections formed therelroin, such polygonal formation extending from substantially the top of the cap to the rolled edge of the skirt on the inside and so proportioned as to frictionally engage the outer faces oi container projections.

6. A metal cap comprising a top and a depending polygonally formed skirt or flange provided with inwardly extending projections therebelow, the angle formed by a pair of said polygonally formed portions intersecting one oi said projections.

T. A- metal cap comprising a top having a depending polygonally formed flange or skirt provided at its lower edge with a stren thened portion having inwardly extending projections, the angle formed by a pair of said polygonally formed portions intersecting one of the locking projections.

8. A metal cap comprising a top having a depending shallow polygonally formed flange or skirt having its lower edge curled, rolled or beaded to reinforce the same and having formed therefrom inwardly extending locking projections, the angle of a pair oi said polygonally formed portions intersecting said locking projections.

9. A metal cap comprising a top having a shallow decagonally tormed flange or skirt tcrn'iinating in a rolled, curled or beaded lower edge provided with a pair of diametrically opposed locking projections, the angle formed by a pair of said decagonally termed portions intersecting one of said projections.

10. A container cap comprising a top and a depending shallow flange or skirt of metal havin a curled, rolled or beaded lower edge, and a pair of diametrically opposed inwardly extending locking lugs formed from such rolled edge, the entire skirt from substantially the top of the cap to the rolled lower edge having on both the inside and the outside thereof a continuous series of wide angularly connected surfaces forming substantially a polygon so proportioned as to frictionally engage the outer faces of container projections. I

11. A metal cap comprising a top having a shallow depending flange or skirt provided with a. curled, rolled or strengthened lower edge having a pair of diametrically opposed inwardly extending projections formed from such rolled edge, said skirt having a polygonal formation from substantially the top to-substantially the strengthened lower edge of the skirt, the angle of a pair of said polygonally formed portions intersecting a projection.

12. A metal cap comprising a top and a depending shallow flange or skirt provided with a strengthened lower edge and inwardly extending locking projections, said skirt having a polygonal formation from substantially the'top to substantially the lower strengthened edge of the skirt, the angle formed by a pair of said polygonally formed portions intersecting a projection.

13. A container cap comprising a top and a depending polygonally formed flange or skirt of metal provided with a rolled, curled or beaded lower edge and inwardly extending locking lugs, such polygonal formation being so proportioned as to frictionally engage the outer faces of inclined container projections.
